The correct answer is A. The show was awarded a prize by the local drama club.
Step-by-step explanation:
In the English language, the active voice follows a subject, verb, and object structure. On the opposite, in the passive voice, the object is the first element, followed by a verb that includes a form of the verb to be or auxiliary and the main verb in past participle, and finally, the verb is followed by the subject, although this can be omitted. In this way, the subject is the least important element or it is passive. According to this, the passive voice sentence is "The show was awarded a prize by the local drama club" as in this the object is first "the show", then the verb includes the auxiliary verb "was" and the past participle "awarded" and finally there is the subject the local drama club.
